This Robert Wood Johnson Foundation-funded analysis presents what we know about the provision of medically inappropriate and unnecessary services that drive up health care spending without making a positive impact on patients' health outcomes. It also describes approaches that have already been used to address this issue—with limited success. We suggest that broader payment reforms are needed to minimize incentives to overdiagnose and overtreat and to better support the other approaches.
